The structure of the part number (5L3E...) indicates a specific model year and likely the system the part belongs to. To find out exactly what it is, you would need to:
* Use a Ford parts website: Enter the part number into a Ford parts website or a reputable online parts retailer that specializes in Ford vehicles.
* Consult a Ford parts catalog: A physical or digital parts catalog for the appropriate Ford F-150 model year should list the part and its description.
* Check a Ford dealership: A Ford dealership's parts department will have access to the most accurate information.
In short, the number itself doesn't tell you what the part *is*, only that it's a specific Ford part for an F-150. You need to use the number to look up the description.
